Roundup: Killzones and time windows, fixed clocks, volume bursts and session allowlists
Time-based trading comes up a lot here under different names: killzones, silver bullet windows, time-of-day filters, session allowlists. Six threads cover it from different angles. Here's what they agree on and where they don't.
Why time matters at all
The time-of-day filters thread makes the case with your own data. Break your trades down by session and hour, and the edge often concentrates in one window. A breakout strategy might do best at the London open, a range approach in quiet Asia. A reply adds the finding most people get when they actually do it: the last hour of the session tends to look worst, partly market and partly fatigue. Another reply warns to use one consistent time zone in the journal, because mixing local and platform time across months makes the hourly breakdown useless.
The liquidity map thread explains part of the why. Majors are cheapest and deepest when their home markets are open: EURUSD and GBPUSD through London and the overlap, USDJPY in Tokyo and New York, AUD and NZD in their own mornings. A reply notes the late New York into early Asia gap is the window to avoid on almost everything, with wide spreads and little movement. Another, from someone on Lagos time, points out the London and New York overlap lands in the afternoon there, which suits anyone working mornings.
Fixed windows
The silver bullet thread describes the idea in its simplest form: one or two short windows, like an hour after the London open and an hour after the New York open, and nothing outside them. A reply raises a calendar issue worth checking before testing: a New York window starting at 8:30 New York time lands right on many US releases, so you're partly testing news reactions, not the window.
The danger windows thread maps the predictable times to avoid: rollover at 5pm New York, the minutes around high-impact releases, holidays and the thin hours. A reply explains why stops get hit at rollover when the chart shows price never touched them: charts usually show the bid, and short stops trigger on the ask. Turning on the ask line in MT4 or MT5 makes that visible.
A clock or a condition?
The volume burst thread is the most interesting one. It keeps a fixed outer window, say 07:00 to 10:00 London, but only looks for continuation setups after M1 tick volume exceeds roughly twice the previous hour's average. Before the burst, watch but don't trade. The idea is that the clock tells you when activity usually starts, and the volume tells you whether it actually did today. It was still an experiment in that thread, so treat it as an idea to test, not a finding.
Taking the decision away from yourself
The allowlist thread solves a different problem. A simple gate, in code or even a spreadsheet flag: Asia mostly off, London on, overlap on with tighter filters, late NY reduced. Off means off, so a candle that looks too good at 03:00 doesn't become a trade. On still requires the normal spread and news checks.
Where they differ
The fixed-window camp values simplicity and testability. The volume-burst approach adds a condition that might filter dead days but is harder to test fairly. Both agree on the starting point: find your own best hours from the journal before borrowing anyone's killzone.
Have you split your results by hour? Did your best window match the textbook killzones or something else?
